Answer:
21 to 3
70 to 10
Step-by-step explanation:
28÷7 = 4
21÷7 = 3
70÷7 = 10
6a
So you would write the factored equation as 6a(b+2)
Answer:the warehouse's width is 100 feet.
Step-by-step explanation:
Let L represent the length of the rectangular warehouse.
Let W represent the width of the rectangular warehouse.
The rectangular warehouse was 20 feet longer than 3 times its width. This means that
L = 3W + 20
The perimeter of a rectangle is
the sum of all its sides. Therefore, the formula for determining the perimeter of a rectangle expressed as
Perimeter = (L + W)
If the perimeter of the warehouse was 840 feet, it means that
2(L + W) = 840
Dividing through by 2, it becomes
L + W = 420- - - - - - - - 1
Substituting L = 3W + 20 into equation 1, it becomes
3W + 20 + W = 420
4W = 420 - 20
4W = 400
W = 400/4 = 100
Slope = y2-y1 / x2-x1
= 24-19/9-4
= 5/5
= 1
solve for b
y=1x+b
19=1(4)+b
19=4+b
15=b
the equation of the line is y=x+15
